Car has 69k miles.There is an intermittent rattling noise coming from around the bell housing. I've only heard it twice at idle but last night sounded horrible. The engine seems the be running fine oil pressure was at 40psi and temp at 210, I would hear it lightly when I'm in 2-6 rpms below 2k when I would stomp on the accelerator pedal. I will be dropping the trans to find the problem, but has anyone had a similar problem like this? I'm hopping it's something with the clutch

I was able to check it and when I tapped the y-pipe with my hand I heard a light rattle from the o2 sensor heat protector sleeve collar. I'm making a hanger for my exhaust dump and see if it help some, I'm going to check it again

Nice, gotta hate a rattle, especially one you can't locate. At least you don't have to drop the trans. :-)

I'm glad I don't,lol my first thought was my clutch was done but I didn't hear the noise anymore. What through me off was my oil level was less than 1quart low, there is no smoke coming from the exhaust. All I see is the down pipe wet with water
